DESCRIPTION:

BRIEF SUMMARY
CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based upon PCT Application Ser. No. PCT/EP 94/02700, filed Aug. 12, 1994, which claims priority from European Patent Application Serial No. 93.202.440.9, filed on Aug. 19, 1993.
The present invention relates to novel substituted dihydropyranopyridines, processes for their preparations, pharmaceutical compositions containing them and their use as a medicine, in particular for the prevention or treatment of disorders characterized by excessive vasodilatation, especially migraine.
Migraine is a non-lethal disease suffered by one in ten individuals. The main symptom is headache; other symptoms include vomiting and photophobia. For many years the most widely used treatment for migraine involved the administration of ergotalkaloids, which show however several adverse side effects. Recently a tryptamine derivative, i.e. sumatriptan, was introduced as a novel antimigraine drug. We have now surprisingly found that the present novel substituted dihydropyranopyridines show 5-HT.sub.1 -like agonistic activity and can thus be used in the treatment of disorders characterized by excessive vasodilatation, especially migraine.
The present invention is concerned with compounds of formula ##STR3## the pharmaceutically acceptable acid addition salts thereof, the N-oxides thereof and the stereochemically isomeric forms thereof, wherein .dbd.a.sub.1 --a.sub.2 .dbd.a.sub.3 --a.sub.4 .dbd. is a bivalent radical of formula: substituted by halo, hydroxy, C.sub.1-6 alkyl or C.sub.1-6 alkyloxy;
R.sup.1 is hydrogen or C.sub.1-6 alkyl;
R.sup.2 is hydrogen or C.sub.1-6 alkyl;
R.sup.3 is hydrogen or C.sub.1-6 alkyl;
Alk.sup.1 is C.sub.1-5 alkanediyl;
Alk.sup.2 is C.sub.2-15 alkanediyl;
Q is a radical of formula ##STR4## wherein
R.sup.4 is hydrogen, cyano, aminocarbonyl or C.sub.1-6 alkyl;
R.sup.5 is hydrogen, C.sub.1-6 alkyl, C.sub.3-6 alkenyl or C.sub.3-6 alkynyl;
R.sup.6 is hydrogen or C.sub.1-6 alkyl; or
R.sup.5 and R.sup.6 taken together may form a bivalent radical of formula --(CH.sub.2).sub.4 -- or --(CH.sub.2).sub.5 --;
R.sup.7 and R.sup.8 each independently are hydrogen, hydroxy, halo, C.sub.1-6 alkyl, C.sub.1-6 alkyloxy, aryloxy, C.sub.1-6 alkylthio, cyano, amino, mono- or di(C.sub.1-6 alkyl)amino, mono- or di(C.sub.3-6 cycloalkyl)amino, aminocarbonyl, C.sub.1-6 alkyloxycarbonylamino, C.sub.1-6 alkylaminocarbonylamino, piperidinyl, pyrrolidinyl;
R.sup.9 is hydrogen, hydroxy, halo, C.sub.1-6 alkyl, C.sub.1-6 alkyloxy, aryloxy, C.sub.1-6 alkylthio, cyano, amino, mono- or di(C.sub.1-6 alkyl)amino, mono- or di(C.sub.3-6 cycloalkyl)amino, aminocarbonyl, C.sub.1-6 alkyloxycarbonylamino, C.sub.1-6 alkylaminocarbonylamino, piperidinyl, pyrrolidinyl;
R.sup.10 is hydrogen, C.sub.1-6 alkyl, C.sub.1-6 alkylcarbonyl, or aryl C.sub.1-6 alkyl;
R.sup.11 and R.sup.12 are hydrogen or taken together with the carbon atom to which they are connected form C(O);
q is 1 or 2;
R.sup.13 is hydrogen, C.sub.1-6 alkyl, C.sub.1-6 alkylcarbonyl, or arylC.sub.1-6 alkyl;
R.sup.14 is hydrogen, hydroxy, halo, C.sub.1-6 alkyl, C.sub.1-6 alkyloxy, aryloxy, C.sub.1-6 alkylthio, cyano, amino, mono- or di(C.sub.1-6 alkyl)amino, mono- or di(C.sub.3-6 cycloalkyl)amino, aminocarbonyl, C.sub.1-6 alkyloxycarbonylamino, C.sub.1-6 alkylaminocarbonylamino, piperidinyl, pyrrolidinyl;
R.sup.15 and R.sup.16 each independently are hydrogen, hydroxy, halo, C.sub.1-6 alkyl, C.sub.1-6 alkyloxy, aryloxy, C.sub.1-6 alkylthio, cyano, amino, mono- or di(C.sub.1-6 alkyl)amino, mono- or di(C.sub.3-6 cycloalkyl)amino, aminocarbonyl, C.sub.1-6 alkyloxycarbonylamino, C.sub.1-6 alkylaminocarbonylamino, piperidinyl, pyrrolidinyl;
R.sup.17 and R.sup.18 each independently are hydrogen, hydroxy, halo, C.sub.1-6 alkyl, C.sub.1-6 alkyloxy, aryloxy, C.sub.1-6 alkylthio, cyano, amino, mono- or di(C.sub.1-6 alkyl)amino, mono- or di(C.sub.3-6 cycloalkyl)amino, aminocarbonyl, C.sub.1-6 alkyloxycarbonylamino, C.sub.1-6 alkylaminocarbonylamino, piperidinyl, pyrrolidinyl;
R.sup.19 and R.sup.20 each independently are hydrogen, hydroxy, halo, C.sub
